I have a 2015 VW Passat. TSI engine 1.8.
In the defrost duct on the instrument panel flap adjust motor is down in the open position. This is causing frost on the outside of the windshield.
We opened the panel to see if we can some how mechanically close the flap. Failed. Assembled the panel back. now I get hot...very hot Air on the drivers side & Defrost duct and cold air on the passenger side. Please help Thanks
